M lTER-BOX.

SPECIFICATION forming part of Letters Patent No. 613,189, dated October 25, 1898.

Application filed March 26, 1897. Serial No. 629,361 (No model.)

To all whom it may concern.-

Be it known that I, HIRAM L. COOPER, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Miter-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to new and usefulimprovements in miter-boxes; and it consists in the construction and arrangement of parts, as hereinafter fully set forth, and pointed out particularly in the claim.

The object of the invention is to provide a miter-box having a stationary base upon which a revoluble table is adapted to be mounted, said table being provided with angled sides and work-clamps, also an independently-movable saw-guide, which object is attained by the construction illustrated in the accompanying drawings, in which- Figure 1 is a general perspective view of a miter-box as made in accordance with my invention. Fig. 2 is a similar View of the rear side of Fig. 1. Fig. 3 is a central vertical section through Fig. 1. Fig. lis an enlarged detail of the saw-guide.

Referring to the numerals of reference, 1 designates the base, which may be rectangular incontour or of other suitable formation, said base being provided with spurs 2, which serve to better hold it in any desired position. Pivoted to the diametrical center of said base is a table 3, said table being pivoted by means of a bolt 4, the head of which rests upon the upper face of table 3, and its lower end being provided with a nut which is sunk within bottom 5 of the saw-guide, by which arrangement the table, saw-guide, and base 1 are united by a single connection.

Bigidly mounted upon the upper face of table 3 are blocks 6, said blocks having wings 7 formed integral therewith and rising therefrom.

8 8 indicate knees which are secured to said wings and to the table, so as to give additional strength to said Wings to withstand the pressure which they receive, as hereinafter referred to.

9 9 represent metal yokes, one leg of each of which is adapted to lie upon the upper faces of blocks 6 and rigidly secured to angleirons 9, and their lower legs are adapted to enter recesses (not shown) in the under face of table 3.

1O designates bolts which are adapted to be screwed, by means of thumb-nuts 10, into threaded apertures formed in table 3 and blocks 6 to move said yoke and clampingplate 9 in the direction of the adjacent wing 7 and to bind any piece of work that may be placed upon the block 6 lying between said clamping-plate and wing.

The saw-guide consists of a bottom piece 11, having guide-blocks 12 with a saw-space therebetween mounted thereon, one of said saw-guides being cut away at 12 to form an opening or escape for sawdust. The rear portion of the bottom of the saw-guide is enlarged horizontally and provided with a slot 13, curved concentric with the pivot-bolt 4.

14 indicates a bolt the head of which is provided with an angled portion, said head and angled portion being sunk flush with the under face of table 3, the body of the bolt projecting upward through said table and slot 13 and receiving a thumb-nut 15 upon its upper threaded end.

The pivot-bolt 4 extends through the bottom 5 of the sawguide, where its head is countersunk, as shown, and as the slot 13 is curved concentric thereto the guide may be adjusted right or left around the said pivot to any desired point. In order that the thumbnut 15 may not interfere with the guide as it is swung from side to side, the opening 12' is carried backward a suificient distance to extend over the slot 13, as shown in Fig. 3, to provide a free passage for the nut.

It will be apparent from this construction that the saw-guide may be moved in the direction of a horizontal circle independent of base 1 and table 3, but is capable of being locked to said table when desired by means of nut 15.

It will thus be seen that the construction and arrangement of parts hereinbefore set forth produce a miter box that may be cheaply manufactured and one in which various angles or miters may be cut and the parts adjusted and locked when a number of pieces which are to have the same bevel are desired to be sawed.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

In a miter-box, the combination of the base 1, the table pivoted thereto by means of a bolt 4, the adjustable saw-guide, consisting of a base 11 and guide-blocks 12, the base of said saw-guide being enlarged and having a curved slot formed therein, the bolt 14: having its angled portion and head let into the under face of table 3, so that its shank may
